【発明の詳細な説明】 産業上の利用分野 この発明は、例えば自動車用サスペンション等の防振部
材を支持するために用いられる防振ゴムブッシュに関す
る。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-vibration rubber bush used for supporting an anti-vibration member such as an automobile suspension.

ッションロッドブッシュが用いられる場合がある。2. Description of the Related Art For example, a compression rod bush may be used to support a compression rod on one end side of a transverse link of an automobile on a vehicle body.
このコンプレッションロッドブッシュは、例えば特開昭
６１−２２３３４４号公報に示されているように、ゴム
材を有する有底筒状のもので、内部にコンプレッション
ロッドを挿入する差込み孔が形成されている。This compression rod bush is, for example, as disclosed in Japanese Patent Laid-Open No. 61-223344, has a bottomed cylindrical shape having a rubber material, and has an insertion hole into which the compression rod is inserted.
したがって、トランスバースリンクの振動によりコンプ
レッションロッドがその軸方向あるいは軸方向に交叉す
る方向に振動した場合にこの振動を前記ゴム材によって
吸収してシミー性能の向上等を図るようになっている。Therefore, when the compression rod vibrates in the axial direction or in the direction intersecting with the axial direction due to the vibration of the transverse link, the vibration is absorbed by the rubber material to improve the shimmy performance.
しかし、この従来例は、コンプレッションロッドを挿入
するだけでトランスバースリンクを弾性的に支持するこ
とができる点で有利となるが、単一種類のゴム材を用い
た場合には、ロスファクターを高めるには限界があり、
所望の防振性能を得ることができないという問題があ
る。However, this conventional example is advantageous in that the transverse link can be elastically supported simply by inserting the compression rod, but when a single type of rubber material is used, the loss factor is increased. Has limitations,
There is a problem that desired vibration damping performance cannot be obtained.
そこで、例えば実開昭６４−７４２号公報等に記載され

ようにしたものも提供されている。Therefore, for example, as in the invention disclosed in Japanese Utility Model Laid-Open No. 64-742, etc., a metal sleeve is fixed to the outer circumference of an elastic member vulcanized and bonded to the outer circumference of a bottomed inner cylinder.
A bottomed outer cylinder is fixed to the outer periphery of the metal sleeve, and a viscous fluid is filled in a fluid storage space between the outer cylinder and the elastic member so that the loss factor is increased by the viscous fluid. The ones that have been made are also provided.

的に固定するようになっている。DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the latter conventional example, in order to fix the outer cylinder and the metal sleeve, a flange portion provided on one end side of the metal sleeve is provided on one end side of the outer cylinder. The flanged caulking portion is fixed by crimping, and the large diameter portion of the outer cylinder is subjected to diameter reduction processing by means of octagonal drawing to integrally fix the outer diameter portion.
このため、斯かる２重の加工工数により、外筒と金属ス
リーブとの固定加工作業能率が悪化すると共に、加工コ
ストの高騰を招来する。Therefore, due to such double processing man-hours, the work efficiency of fixing the outer cylinder and the metal sleeve is deteriorated, and the processing cost is increased.

共に、重量の増加が余儀なくされる。Moreover, since the fixing flange portion and the flange-shaped crimp portion must be provided in the radial direction at the front end sides of the metal sleeve and the outer cylinder, the outer diameter of the vibration-proof rubber bush is increased accordingly. As a result, the size of the whole becomes large and the weight is inevitably increased.

工作業能率の向上が図れる。The loss factor can be increased by enclosing a liquid between the inner and outer cylinders, and in particular, the peripheral wall of the outer cylinder corresponding to the curved portion previously formed on the peripheral wall of the ring member is simply drawn. Since the outer cylinder can be integrally fixed to the ring member only by this, the fixing work efficiency can be improved.

このため、外径寸法の増加が防止されて、防振ゴムブッ
シュ全体の小型化と軽量化を図ることができる。Moreover, instead of fixing the ring member and the outer cylinder by double processing such as drawing and caulking as in the conventional case,
Since the predetermined peripheral wall of the outer cylinder can be integrally fixed to the ring member by a single drawing process, the fixing work efficiency can be greatly improved and the processing cost can be reduced. Further, as described above, since only a predetermined peripheral wall of the outer cylinder is drawn, a flange portion for caulking and fixing the outer cylinder and the ring member unlike the conventional case is not necessary.
Therefore, an increase in the outer diameter dimension is prevented, and the overall size and weight of the anti-vibration rubber bush can be reduced.
